Plastic clad silica fibers with UV and IR transmission


For medical, scientific and military applications, Fiberguide Industries offers a full line of low and standard hydroxyl concentration (OH) plastic coated silica fibers. The Anhydroguide™ and Superguide™ are low cost optical fibers that provide superior UV and infrared transmissions.

Fiberguide's Anhydroguide fiber is constructed of a pure fused silica core, made by reacting silicon tetrachloride with oxygen using a plasma arc. This ensures a low residual OH for excellent infrared transmission. Superguide's silica core is constructed in the same manner, only with an oxy-hydrogen flame instead of a plasma arc, which maximizes the fiber's UV transmission properties.

Both fibers feature plastic cladding to protect the fiber during buffer stripping and prevent breakage, while increasing fiber strength and reducing static fatigue in humid environments. Fibers offer exceptional transmission in tight bends, with a high core-to-clad ratio and numerical aperture of 0.37. All materials used in construction are certified by NAMSA to USP Class VI for non-toxicity and biocompatibility.
